This series cleans up a few drivers which did this. Actually, as Al pointed out, we do have lifetime rules issues with doing this. The problem is that gendisk itself always has a shorter lifetime than scsi_device (not much shorter, usually, but if you execute a legal ULD unbind manoeuvre you'll end up with a dangling gendisk pointer). The other problem with taking gendisk out of the ULD structure and putting it into the scsi_device is that for the sg driver, we have two of them (one for the attached ULD and one for the sg driver). The fundamental issue seems to be that the gendisk is the holder of all the other info (queue, ULD etc) not vice versa ... and this patch is trying to reverse that relationship.
